MULTIPLEX CELL-DISASSEMBLING PROCESSOR AND MULTIPLEX CELL-DISASSEMBLING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a multiplex cell-disassembling processor with which a buffer capacity and quantity of buffer management information can be reduced and a cell-disassembling time can be decreased. ;SOLUTION: A header/payload separation processing section 11 separates a header part and a payload data part of an ATM cell. A loss error-in delivery processing section 12 conducts cell loss error in delivery detection, cell compensation at detection of cell loss, and cell abort at detection of cell error-in delivery. A common buffer section 14 stores in advance the pattern of a dummy cell and has banks in units of cells storing the payload part of the received ATM cell. A CAM section 16 stores data correlating an ATM/AAL header with an address where the payload is stored. A complementary FIFO section 17 stores data correlating the cell loss number detected by the loss error-in delivery processing section 12, the ATM header and the AAL header with the addresses in which the payload is stored.;COPYRIGHT: (C)2000,JPO
